Problems solved by technology

The reason why the existing glue emits formaldehyde is because its production raw materials contain urea-formaldehyde resin, which is resistant to weak acids and alkalis, has good insulation performance, excellent wear resistance, and is cheap. It is the most widely used variety in adhesives today. Especially in the wood processing industry and the construction industry, and currently urea-formaldehyde resin and its modified products account for about 90% of the total amount of adhesives used. Adhesives containing urea-formaldehyde resin will intensify under high temperature, high humidity, negative pressure and high load conditions. In addition, urea-formaldehyde resin adhesives are easy to decompose when encountering strong acids and alkalis, and have poor weather resistance, poor initial viscosity, large shrinkage, high brittleness, water resistance, and easy aging. In environmental protection and application durability, functionality There are serious flaws in

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to an adhesive for interior decoration and a preparation method thereof. Background technique [0002] Most of the adhesives used in the decoration industry are non-environmentally friendly glues containing free formaldehyde. Although this type of glue is low in price and has good bonding performance, it is self-evident that it brings harm to people's health. The reason why the existing glue emits formaldehyde is because its production raw materials contain urea-formaldehyde resin, which is resistant to weak acids and alkalis, has good insulation performance, excellent wear resistance, and is cheap. It is the most widely used variety in adhesives today. Especially in the wood processing industry and the construction industry, and currently urea-formaldehyde resin and its modified products account for about 90% of the total amount of adhesives used. Adhesives containing urea-formal...
